Added non-functional ActionBar SearchView
Search now links back to ImagesActivity
Imported my Log class

From my open source github project android-utils
Setup recent search suggestion provider
Added volley.jar

If this were a longer-term project I would import this as a submodule so that
it would be easy to update or edit the Volley source.  However, I don't
anticipate this being a long-term project, so a JAR will suffice.
Added basic Volley request queue and sample

Just to prove that the basic flow works
Added simple google image search

To prove that it works
Moved ImagesActivity to ui package

Just to match conventions I use nowadays
Created ImagesFragment, transferred UI to there
Added basic layout for ImagesFragment
Moved Log into the utils package

Better code organization
Imported Ui class from my android-utils lib
Added basic ImagesAdapter

Doesn't do much at the moment
Added data storing/loading Fragment

This is kept in a separate Fragment so that it can be retained across
configuration changes.
